  • Patent number: 11308883
    Abstract: In an example implementation according to aspects of the present disclosure, a system including a controller to receive a temperature value, from a temperature sensor corresponding to a sub-pixel in an organic light emitting display. The controller calculates a luminous value of the sub-pixel based on the temperature value and a function corresponding to a degradation of luminosity over time and temperature. The controller determines, based on the luminous value, a corrected luminous value corresponding to a target luminous value. The controller retrieves a voltage value from a second database, wherein the second database comprises a luminous-voltage relationship. The controller applies the voltage value to the sub-pixel.

  • Patent number: 11244588
    Abstract: A display device includes pixels, a serial-to-parallel converter (SPC), a row driver, a column driver, and a switch. The pixels are arranged in rows and columns which include a first column and a first row. A first pixel resides at an intersection of the first row and first column. The SPC extracts, from a signal sent by a graphics controller, pixel data and a command. The row driver initiates a refresh of the pixels residing in the first row based on the pixel data. The column driver transmits the pixel data to the first column. During the refresh, the switch allows transmission of the pixel data to the first pixel when the command indicates that the first pixel is to be refreshed and prevents transmission of pixel data to the first pixel when the command indicates that the first pixel is not to be refreshed.

  • Patent number: 11228194
    Abstract: A motherboard having a smart charging function is provided. A connection interface is configured to an electrical device. A first controller is coupled to the switching circuit and communicates with the electrical device via a first transmission path. A second controller is coupled to the switching circuit and communicates with the electrical device via a second transmission path. In a standard charge mode, the first transmission path is turned on and the first controller directs a voltage converter circuit to generate first charge power to the electrical device. In a fast charge mode, the first controller determines whether the electrical device has a specific operating system. Responsive to determining that the electrical device does not have the specific operating system, the second transmission path is turned on and the second controller directs the voltage converter circuit to generate second charge power to the electrical device.

  • Publication number: 20220000719
    Abstract: A pill cutter has a base, a clamping assembly, a connecting unit, a cover, and a cutting assembly. The clamping assembly has two first clamping units moveably mounted on the base. The connecting unit has a base end moveably mounted on the base and a cover end pivotally mounted on the cover. The cutting assembly has a pressing unit moveably mounted on the cover and a blade securely mounted on the pressing unit. When the cover is opened, the connecting unit moves along with the cover and pulls the two first clamping units away from each other. When the cover is closed, the two first clamping units move toward each other by springs to stably clamp a pill in any shape or size. Therefore, a user can simply press the pressing unit to move the blade to safely cut the clamped pill.

  • Patent number: 11166873
    Abstract: A pill box has a case holder and multiple pill cases. The case holder is divided into multiple compartments by multiple crosswise partitions, a rear panel and a bottom panel. The pill cases are fitted in the compartments of the case holder. Each pill case is able to pivot relative to the case holder between a close position and an open position. When intending to get pills that are in the pill box, a user can rotate one of the pill cases to the open position. Thus, the pill case protrudes forwardly from the case holder. Accordingly, the pills are able to be precisely poured onto the user's hand.
